Connection-terminal.



A. I'I. WEISS. CONNECTION TERIVIINAI.. APPLICATION FILED SEPT. 3o. 19|5.

@ville-l lll www oonnnoronann ing-atteind To all whom it may cof/mera:

Be it known that l, ALFRED H. "Weiss, a ci tizen of the United States of America, residing in lllilmette, county of Cook, and State oi' lllinois, have invented certain neiv and useful improvements in Connection- Terminals, of which the following isa specification. s

lvly invention relates to connection terminals and has to do more particularly with devices of this character which are provided with locking means 'for securely holding a conductor. My invention is directed more particularly' to devices of the above character in which means is provided for preventing the clamping elements, between which the conductor is securely held, from turning in relation to each other. The present application is a division of my application for junction boxes,vliled December 26, 1912, Serial No. 738,565. u

lvly invention is particularly adapted'for use with the electrical apparatus used in connection with the ignition system ot an automobile. lt is the object of my invention to produce an improved device of the class described which will obviate undesirable features and embody desirablei'eatures and advantages all in a simple, etlicient and economical manner, and to the accomplishment of this object and suoli others as may hereafter appear, the invention consists in the novel details ot construction, parts, and combination of parts hereafter described and particularly pointed out in the appended claims, reference being had to the accompanying drawings forming a. part hereof in which the same reference characters indicate like parts throughout the several views, and in Which Figure l is an elevation of terminal block upon which is a-plurality of terminals oi' my invention are mounted.

Fig. 3 is a right end view of Fig. 2,

Fig. -tis a-sectional view along the line a--fl'ot Fig. 2 showing a conductor con- .neeted tofthe terminal,

Fig. 5 is a sectional view along the line 5 -5 of Fig. 2,

lig. 5 is a view in perspective of the parts oit' the terminal disassembled.

Referring new more detail tcmy Specification of Letters .Patent '$33,565. llivdeil and this application. tiled M tti.,

vention as illustrated, it comprises a` mount-- ing block or strip l of any suitable insulating material such as liber or balrelite, upon which the terminals ot my invention are mounted. ln the draiving,lP have illustrated sin terminals, but will only describe one oli them. Tlhe terminal of my invention comprises a screw-threaded stud 2, extending through a suitable opening 3 in the mount-- ing block or plate l. 'lnh'e screw-threaded stud 2 has a square head 21 which lits into a groove d in the bottom ot' the mounting block l, the said groove il being of a size to receive the square head 21 of the stud 2. llhe groove l runs the Width of the mounting block l and keeps the said stud 2 from twisting around in the opening 3 ot the bloclr l. A, connecting plate member is provided, havinga suitable opening 51 through which the said screw stud 2 passes, the said connecting plate member 5 when in place resting upon the tace of the mounting block l. A U-shaped clamping member 6 is provided having a suitable opening G1 through which .the said stud 2 passes. The clamping inember 6 has two extending legs 62 and 63 which tit into notches 52 in the plate 5, the said legs 62 and 63 also extending into a groove 'l' in the block l. The groove 7 extends the Width of the block and is ot a Width and depth to receive the said dependent legs 62 and 63 of the clamping member rlhe legs G2 and 63 of the member 6 fit into the notches 52 of the plate 5 and prevent the said clamping member 6 `from turning in relation tol plate 5. yThe legs 62 and 63 are of a length to permit larger sized conductors to be clamped between the plates 5 and tl and at the same time prevent the said plate 5 from turning-in relation to plate 5. nut 9 having screw-threaded engagement with the stud EZ clamps the said conductor 8 between the plate 5 and the member el split Washer l0 is placed between the nut 9 and member 6 and acte as a lock tor the nut 9 when the said nut is screwed down tightly to hold the conductor 9 between the 1 plate 5 and clamping memberl Gf Theiplate 5 has an extension 5 which serves as a terminal for the said plate 5.

While l. have described one speci-fic enihcfdinient oli my invention, il do not Wish to be limited to the saine, as it is app prevent the that changes and modifications may be made Without departing from the spirit and scope of the appended claims.

' Having described my invention What I claim as new and desire to secure by United yStates Letters Patent is:

l. A device of the character described including a mounting block, a channel cut in said block, a contact plate mounted upon said block, a U-shaped clamping member adapted to rotation of said clamping mem ber when a conductor is being fastened between said contact plate and said clamping member, a threaded fastening member, provided vvith a lock Washer and a nut, passing through orifices in said contact plate and clamping member to securely hold the conductor between said contact plate and clamping member, and an integrally formed rectangular head for said fastening member adapted to iit into said channel to prevent said fastening member from rotating when said nut is turned to secure said conductor in position.

2. In a device of the' character described,

fit over said contact plate to.

tact plates, a second slot extending across said mounting block, and a fastening member provided with integrally formed sideA pieces bent at right angles to the Contact surface'of said clamping member, thesaid side pieces of the clamping member being adapted to prevent the rotation of said clamping member in relation to said. mounting strip when a conductor is beingclamped in position by said clamping member, an

orifice in both said clamping member and.

said mounting strip, a threaded cylindrical fastening member extending through both of said orifices, a lock washer and a nut for said fastening member for clamping said conductor in position, and a rectangular head for said fastening member adapted to i'it into the said orifice in the mounting strip to prevent said fastening member from rotating when said nut is turned to secure said conductor in place.

Signed by me at Chicago, county of Cook and State of Illinois, n the presence of two `Witnesses.
